To a 2071,0112, it may concern):

Be it known that I, EDWARD L. VIE'rH, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Soldering- Irons,of

which the following is a clear, full, and exact description.

desired.

The object of my invention is to provide a gas-heated soldering-ironwhich can be conveniently used both for domestiowork and at the bench inmachine-shops and which is cheap and sim le in construction and by thesubstitution 0 any one of several bits can be used for either large orsmall work. This I accomplish by the means hereinafter fully described,and as particularly pointed out in the claims.

In the drawings, .Figure 1 is a side view of my improved soldering-iron.

gitudinal central section.

Referring to the drawings, A represents a suitably extcriorly shapedtubular handle Fig. 2 is a lonwhich is preferably made of wood or otherin- I male stub of this gas-cock and leads to and is' connected with agas pipe or main in any suitable manner. To the screw-threaded end ofpipe 1), extending beyond the ferruled end of the handle,.a tubularholder D is secured. This holder consistsof a section of metal pipewhich is preferably about one-half or twothirds the length of pipe I),and near the ham die it is provided with draft-openin s c c, that, asshown in the drawings, are preferably located diametrically oppositeeach other, although they may be differently disposed, if Between theseopenings and the adjaoent 'end of the holder the latter has a bushing Escrewed into its bore. this bushing is closed with the exception of avery small orifice that forms the bore of a jet d; but the diameter ofthe bore of the re maining portion of the bushing is greater,

and the holder-D is secured to the handle by the pipe 6 thereof screwinginto" said bushing. The soldering-bit H is screwed into the end of theholder farthest from the jet. It con- One end of sists of a point of theusual shape having a sharpened or pyramidal-shapedsoldering end and acylindrical body, the end of which farthest from the engaging point isthreaded and screwed into the-adjacent end of the holder farthest fromthe gas-jet and has a longitudinal groove or channel h therein extendingfrom its butt-end to mediate its ends, said channel being deepest at thebutt-end and gradually decreasing in depth as it extends forward. Thescrew-threaded rear end of this bit is screwed into a cup-shaped socketG, the opposite end of which is reduced in diameter and is provided witha nipple g, that is screwed into the bore of its reduced portion and isremovably secured in the end of the holder D by screwing the nipple intothe bore'thereof. The end of the nipple g screwed into the socket Gpreferably extends a distance into the hollow portion or chamber K tonear the soldering-bit H and has its end reduced in diameter to form areduced exit I for the products of combustion as they flow forwardagainst the rear of said bit. When in use, the gases will be soregulated that a. portion thereof will pass directly out through thechannel in the soldering-point, while the remainder will be divertedaround the hollow chamber in the socket and then out, as indicated bythe arrows, thus preventing any back. pressure in the pipe due toextraor dinary accumulation and compression of gas in said chamber.

In operation when the valve B is opened .to permit the gas to flow intothe pipe I) a jet of gas is forced into the holder'D and draws bustionwill to a greater or less extent be held in the chamber K between thehit and the shoulder made by reducing said socket in end increased indiameter, a removable bit inserted the enlarged end of said socket theend of said holder and socket and pro- I jecting into the enlargedportion of the latter.

A soldering-iron comprising a tubular j gitudinally from its retainedend toward its sharpened extremity; a nipple connecting the end of saidholder and socket and proj ecting into the enlarged portion of the latter; a handle, and a tube extending longitudinally through said handlethe extended end of which is screw-threaded and tapped into the portionof the gas-jet havingan enlarged bore.
